RULING MACHINE. 4

My'improved machine is particularly desi ned for ruling electrotypers wax cases made by the depositionof wax upon a metal plate, and my leading objects are to provlde such a machine having capacity for a Wide variety of work; that will produce work with perfect solid joints; and that provides means for effecting accurate micrometer measurements and adjustment by simple mechanical means; I The characteristic features and advantages of my improvements will more fully appear from the following description and the vaccompanying drawings of a preferred embodiment of my invention In the drawings; Fig.1 is a top plan view of amachine embodying my invention with acase fixed thereon Fig.2 is an end view of the machine; Fig. 3 is a side elevation thereof; Fig. 4 is an enlarged transverse sectional view on the line 4:4: of Fig. 1; Fig. '5 is a sectional view on the line 5-5 of Fig.4; Fig. 6 is a sectional View on the line 66 of Fig. 5; Fig. '7 is an elevation of a bracket for supporting the tool carrying mechanism; Fig. 8 is a perspective view of a tool holder on an enlarged scale; and Fig. 9 is a perspective view of a workholding clip on an enlarged scale. v

\s illustrated in the drawings; a pedestal 1 has bolted thereto a bed 2 provided with Ways 3 for supporting the slides'4 of a horizontally reciprocable carriage 5. A rack 6, fixed to one of the slides'of the' table, meshes with a pinion 7 projecting through a bed apertureS and fixed on 'a shaft'9' which is journalled in the bed bearingslO. The shaft 9 has fixed thereon a gearwheel ll rjotatable by a smaller gear'whee'l 12 fixed" on the journalled shaft 13 ofa hand wheel 14. The movement of the carriage by the mechanism is indicatedon the carriage scale 15 ,by a pointer 16'fixed to the bed.

A rotary'table 17 is 'journalled relatively to the carriage 5 by a shaft 18 and is provided with depending circular flanges 19, 19 sliding over the surface of the carriage. conoidal rack '20, fixed 'tothe' flange 19, meshes with a bevel pinion 21 fixed on a shaft 22. "The latter is journalle'dfin' a hearing. 23" dependingtram thetable and has there'oiia bevel gear 24 meshing with a'bevel gear 25 fixed on a journ'alled shaft- 26 and rotatable by a detachable handle 27F cessed to receive the rails.

A bracket43 on the carriage 42 has our- The periphery of the table contains notches-28 for the engagement of a spring pressed pin or detent 29 housed in a bearing 30 on the bed, the pin being providedwith a knurled head 31 for retracting it from a notch.

The surface of the table contains a plural-, ity of undercut grooves 32 preferably intersecting at right angles. I

The undercut grooves contain work holders comprising channeled blocks 33 having tenons 3% extending upwardly through the grooves and flanged Work-holding clips 35 connected with the blocks .by'screws36,the clips having their edges recessed to accommodate the edges of the wax coated metal plate 36 forming the electrot-yPerscase to be ruled. I

A burner low the bed andtable and supplied with fuel through the valve controlled pipe 38 to furnish heat 'for'maintaining the wax of the case at the prop erconsistency. I .I Brackets :39 fixed to. the. bed 2 provide supports for a beam lOexten'ding' across the machine abovethe-table; the beam having 37 is housed inthe pedestal beon its face undercut rails 41 forming slid'eways for the :tool carriage 42 which is. re-

. The tool slide 49 has hinged thereto'by a pintle 52a' door 5 2'held shut by .a thumbnut 53 for securing in the socket or chamber '54" a tool holder 55 having an irregular contour conforming with the contou'r'of the socket 54L, so'that the protuberances of one part register with recesses'of the other part and longitudinal movement of the tool holderist'hereby prevented. The tools 56 required forditferent kinds of work are respectively clamped in similar slotted tool holders by clamps57 and longitudinally adj usted therein by the threaded bolts and nuts '58 so that substitution of- -tools' in the machine may "be quickly and simply made by The'lower endof the shaft makes a merely opening the gate 5-2, replacing the tool holder and locking the gate. v

A pair of undercut slides 59, 59 are movable on the dovetail tenon 60 of the carriage 42 by the, engagement of pinsv 61 thereon with eccentric slots 62 of a disk 63 journalled on the carriage between the slides and rotatable by a handle 64. The slides 59, 59 are provided with rearwardly extending extensions containing seats for semicircular threaded segi-nents 65, 65, forming a split nut mo able by the operation of the slides in" and out of engagement with a threaded shaft or screw 66, theunthreaded end-s otihe shalt beii'ig journ'alled in the brackets 39. A hand wheel 67 is fixed on one end of the shaft 66, and has upon the periphery thereof three scales 68, 68, and 68" cooperating with the pointers 69, 69 and 69" so that a microi n'ete adjustment of the movement and position of the tool carriage may be effected, the plurality oft scales permitting adjustment to various minute fractions of an inch without confusion.

a In the operation oi the machine, a case or 'wax coated plate, upon which desiredtypographical matter, other than lines, has been impressed, is clamped upon thetable- 17 by means of the work holders et, 35 and in a position depending upon the cl-laractor of the lines to be out in the Wax. A tool holder 55, containing a tool 56 suitable for performing the workto bedone, is clampedin the tool slide 49 by the gate 52. The work and tool are then positioned by adjust ment of their respective carriers until the point of the tool is at the desired starting point. The depth of cut of the tool is accurately adjusted by turning the handle 48 until the pointer 47 and scale 46 indicate that the tool has been moved down into properposition. The tool is then moved relatively to the Work by' rotating the hand wheel 67 until a line of desired length has been cut, as indicated by the pointers 69, 6.9'iand 69- on the scales 681, '68 and 68". The handle 64 may be. then moved to, rotate the disk 63 and retract the slides 59, 59 and open the threaded jaws or nut sections 65, 65 sothat the tool carriage'ca'n be moved freely along the, rail 41. Tliie position of the work is again. adjusted by operating the hand wheel 14 and the handle 27, or either of them, andv the cutter 56 is vertically positioned and its cutting depth regulated by operating the handle l8. '1 he tool carriage is connected withthe screw 66 by operating the handle 6st and the; tool is advanced to the work by operating the handle 67;. 7

By my machine, any desired arrangement of lines can he quickly and accurately out in the Wax without necessity for the employ e-nt of a highly skilled operative, since the adjustments are clearly indicated on the scales provided and are effected through mechanical means which are simple in construction and operation.
